        <h2><i class="fa fa-flask"></i> Dimensional data</h2>
        <p>Prometheus implements a highly dimensional data model. Time series are identified by a metric name and a set of key-value pairs.</p>

      <a href="/docs/prometheus/latest/querying/basics/">
        <h2><i class="fa fa-search"></i> Powerful queries</h2>
        <p>PromQL allows slicing and dicing of collected time series data in order to generate ad-hoc graphs, tables, and alerts.</p>

      <a href="/docs/visualization/grafana/">
        <h2><i class="fa fa-line-chart"></i> Great visualization</h2>
        <p>Prometheus has multiple modes for visualizing data: a built-in expression browser, Grafana integration, and a console template language.</p>

      <a href="/docs/prometheus/latest/storage/">
        <h2><i class="fa fa-database"></i> Efficient storage</h2>
        <p>Prometheus stores time series in memory and on local disk in an efficient custom format. Scaling is achieved by functional sharding and federation.</p>

        <h2><i class="fa fa-cog"></i> Simple operation</h2>
        <p>Each server is independent for reliability, relying only on local storage. Written in Go, all binaries are statically linked and easy to deploy.</p>
